Aircraft Maintenance

TSC offers high quality, customer-oriented maintenance solutions for aircraft owners and operators. TSC offers personalized care of customer aircraft, high quality workmanship, and detailed electronic compliance tracking. A cornerstone of our work is our high degree of correspondence and timeliness in project completion.

Our facilities located at Plymouth Municipal Airport KPYM and Michael J Smith Field KMRH offer full service inspections and repairs of piston aviation aircraft. Our team of A&Ps and A&P/IAs are not just experienced mechanics, they’re also pilots. That pilot experience provides our mechanics with a better understanding of owner reported squawks beyond solely an A&P level of experience.
